Precision m5510 screen flicker and BIOS

Got my Precision m5510 last week. Was on bios 1.2.0. Screen was flawless, and premiercolor is amazing.

Yesterday I upgraded to the new 1.2.10 bios. Amazingly, after I installed this new bios, I started getting intermittent screen flickering on lower brightness settings. It wasn't a pulsing or regular flickering. It was instead like seeing micro flashes to a higher or lower brightness. Couldn't find a regular pattern in the flickering, completely random.

Most visible on lower brightnesses, but I even noticed it flickering a little on the higher brightnesses too.

I downgraded my bios back to 1.2.0, and the issue has gone away!!! I'm pretty sure there's something wrong with the 1.2.10 bios. It says its supposed to fix screen flickering (and Issue I never had in the first place), but instead, the new bios gave my computer flickering issues.

I currently have a Service Request in with Dell about the issue, but I wanted to see if other are reporting similar issues.

thanks.
